A researcher wants to test if there is a significance difference between the BMI of regular sugary beverage drinkers in 2010 (me

an BMI = 26.5, reported by the National Health Survey, regular sugary beverage drinker defined as at least 1 sugary beverage drink daily) and in 2015. In December of 2015, the researcher collected a sample of 114 regular sugary beverage drinkers, she measured their BMls and found that the average BMI was 29 with a standard deviation of 3.
1. Which one of the following conclusions is INCORRECT?
a. After conducting the hypothesis testing procedure, the conclusion should be to accept (or fail to reject) the null hypothesis.
b. The critical test statisticis is t = 1.960.
c. The obtained test statistic is t = 8.898.
d. The null hypothesis is that the BMI of regular sugary beverage drinkers in 2010 does not differ from that in 2015.

write an equation in slope intercept form for the line that passes through the point, and is perpendicular to the line y=-1/3x+9
aleksklad [387]

Answer:

Step-by-step explanation:

y=-1/3x+9

This is written in the format y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).

Perpendicular lines have a slope that is the negative inverse of the slope of the reference line, in this case -(1/3).  The new slope is 3.  equation is:

y = 3x + b

To find b, enter the given point, (-6,-2) and solve for b:

y = 3x + b

-2 = 3(-6) + b

-2 = -18 + b

b = 16

The full equation is y=3x + 18

The median of the data set is 81. What number is missing?<br><br> 82, 87, _, 77, 70, 80, 88
mina [271]
Median is the middle number.
Rearrange the numbers to smallest to biggest.
70, 77, 80, _, 82, 87, 88
If the median of the data set is 81 the middle number needs to be 81.
So the missing number is 81.
70, 77, 80, 81, 82, 87, 88

What are the x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2? x = (
Contact [7]

Answer:

(0, 1)

Step-by-step explanation:

In the picture attached, the question is shown.

From the picture:

  • x2 = -4 (x-coordinate of the endpoint)
  • y2 = 9 (y-coordinate of the endpoint)
  • x1 = 2 (x-coordinate of the startpoint)
  • y1 = -3 (y-coordinate of the startpoint)

Ratio m:n, means that m = 1 and n = 2.

Replacing into the formulas:

x-coordinate = m/(m+n) * (x2- x1) + x1 = 1/3 * (-4 - 2) + 2 = 0

y-coordinate = m/(m+n) * (y2- y1) + y1 = 1/3 * (9 - (-3)) + (-3) = 1
